S524A40X10/40X20/40X40
1K/2K/4K-bit Serial EEPROM for Low Power with software write protect
Data Sheet
OVERVIEW
The S524A40X10/40X20/40X40 serial EEPROM has a 1,024/2,048/4,096-bit (128/256/512-byte) capacity, supporting the standard I2C™-bus serial interface.
It is fabricated using Samsung’ s most advanced
CMOS technology.
It has been developed for low power and low
voltage applications (1.
8 V to 5.
5 V).
Important features are a hardware-based write protection circuit for the entire memory area and software-based write protection logic for the lower 128 bytes.
Hardware-based write protection is controlled by the state of the write-protect (WP) pin.
The software-based method is one-time pro...
